Description
Technical field
The present invention relates to fibre faceplate production fields, more particularly to a kind of large area fibre faceplate compacting tool set and production
Method.
Background technique
High-performance optical fiber panel (hereinafter referred to as fibre faceplate) is by the thousands of compact arranged light guides of rule
Fiber optic component of the fiber by processes machine-shapings such as plate-laying, hot melt pressure, annealing, roughing and finishing, it optically has
Have that optical transmission efficiency is high, interstage coupling loss is small, passes as the features such as clear true, zero thickness.Fibre faceplate is widely used in respectively
Kind cathode-ray tube, pick-up tube, CCD are coupled and other need to transmit in the instrument and equipment of image.Most typical application is to make
For the optics input of gleam image intensifier, output window, play an important role to the quality for improving image device.Wherein large area
Fibre faceplate is then the Primary Component for making big visual field low-light level imaging device.Its application field is very extensive: medical field
(such as X-ray machine), industrial X-ray scanning field, industrial X-ray field of detecting and palmmprint scanning field can use the product.With
Scientific technological advance, these field devices imaging viewing field is required constantly to expand, therefore research and development of more large area fibre faceplate
It is increasingly important.
Currently, the manufacturing technology of existing large area fibre faceplate, be continue to use the horizontal compression mould of old optical fiber to it is other related
On the basis of equipment (most of mold and equipment have carried out larger design), first to mold under high temperature, high vacuum environment
Apply high pressure, prepares large volume fibre faceplate blank, be cut to piece then to obtain large area fibre faceplate blank.For
The center edge temperature difference of control large volume blank during fusion pressure.Using multiplicating " heating (or cooling)+heat preservation "
Method, significantly reduce inside heating furnace rate temperature change, extend hot melt pressure activity time；In order to control large volume blank
Upper and lower temperature difference during fusion pressure, the method which uses adjustment furnace temp vertical gradient distribution.
For existing technology, it is desirable to be cut into qualified large area fibre faceplate, just must first prepare qualification
Large volume fibre faceplate blank.But since quality volume is big, equipment requirement is high and easy the problems such as bursting, qualified large volume
Fibre faceplate blank is upper very difficult in preparation.In addition, existing large volume fibre faceplate blank preparation process is still immature, deposit
Many insufficient.Specifically there is following four aspect:
1) blank plate-laying, hot melt pressure and annealing time are too long
Hot melt pressure and annealing aspect, due to the prior art be by significantly reduce inside heating furnace rate temperature change come
The thermal stress that control large volume blank generates in hot melt pressure and annealing process, therefore its process time is inevitably very big
Extend.According to primary Calculation, primary hot melt pressure is completed with existing technique and annealing operation at least needs 95 hours, at about 4 days
Between.
In terms of plate-laying, in order to control the gap between composite fiber, its tightly packed degree is improved, prior art technology is adopted
It is the method for artificial plate-laying.Include at least tens of thousands of composite fibers inside general large volume fibre faceplate, therefore completes one
Secondary qualification plate-laying the amount of time required is very long.
2) adjustment of heating furnace high-temperature area is not flexible

Base vertical temperature difference.The maximum drawback of the technique is exactly to operate extremely to bother.Warm area of every adjustment must all add the whole series
Hot equipment carries out disassembly and re-assemble operation.In order to search out appropriate warm area distribution, carry out test of many times and adjustment be
It is inevitable.Therefore this method is although possible in theory, but the workload that operates is huge, and it is big to practice difficulty, spends the time
Also more, continually disassembly and assembly can also have an impact the service life of equipment.
3) various hot melt pressure equipment volume quality are excessive
Existing large volume blank technology of preparing has continued to use the equipment such as old mold and heating furnace.And the design of old mold is deposited
In some problems --- Redundancy Design is more and force structure is unreasonable.These problems cause its design volume bigger than normal.With compacting
Blank volume size increases, and this problem of mold is more obvious.According to primary Calculation, in order to suppress cross section opposite side size
The large volume blank of 200mm, mold inner-cavity cross-sectional length must at least reach 400mm, in addition mold overall dimensions are more after outline border
Greatly.In view of the high density of its rapidoprint (hot die steel), such mold weight is considerably beyond general mold.This is undoubtedly
Enter furnace and come out of the stove to increase many difficulty and risk to mold.And in order to smoothly load this big mold, heating furnace volume
(4 times of almost existing heating furnace volume) must be increased together, for a high-temperature heating device, volume is bigger,
Processing loss, operation difficulty, operational risk and security risk etc. are also bigger.
4) it injects capital into more
Large area fibre faceplate is prepared with existing technology, then must increase artificial, equipment and time investment, it is contemplated that behaviour
Make the factors such as difficulty and risk, it is necessary to while carrying out the research and development of some auxiliary processes and equipment.Such capital investment is phase
When big.
As described above, the preparation process of existing large volume fibre faceplate blank is many and diverse, high risk, high time-consuming and height are thrown
Enter.

The process basic procedure that preference of the present invention uses for " plate-laying-is die-filling-hot melt pressure-annealing-demoulding-
Cold working ".And " plate-laying ", " hot melt is pressed " and " annealing " process are optimized.
The present invention uses completely new plate-laying method --- and vibration plate-laying is given up used in large volume fibre faceplate production process
Artificial plate-laying technique.Vibration plate-laying is to generate the special installation shaken by connecting, and plate-laying mold continuous vibration is allowed, to promote
The complex light fibril for being put into mould inside is set to be automatically performed closelypacked technique.Using the technique, operator is only needed in batches
It is secondary that complex light fibril is inserted into plate-laying mold, it then periodically completes to check.Through practicing, guaranteeing that plate-laying effect is constant
Under the premise of, which can shorten for about 66% plate-laying time, improve plate-laying efficiency.
Optimization of the present invention for hot melt pressure and annealing process, be divided into three aspects: the time shortens, debugs optimization and equipment
It simplifies.
1. the time shortens
The research and development of new mold and the diminution of blank volume are the key that shorten hot melt pressure and annealing time.
The mold high-performance heat-conducting plate is introduced into mold inner-cavity (heat-conducting plate quantity can blank thickness as needed do spirit
Adjustment living), " cutting " is carried out to large volume screen section blank, direct pressing goes out large area panel blank.Due to steel thermal coefficient
(35~64) are significantly larger than glass (0.5~1.0), therefore during heating (or cooling), heat-conducting plate faster reaches than glass
Assigned temperature.And high temperature (or low temperature) heat-conducting plate connects glass screen section cross section for as new heat source (or absorber)
Touch type heat-conductive.It is thermally conductive that this heat-conducting mode speed is higher than radiation.
In the temperature rise period, the introducing of internal new heat source and high-efficiency heat conduction mode, so that the screen section whole heating-up time shortens.Through
The time spent in practice, glass screen section is raised to safely assigned temperature, shorten to 4~6h from 13~17h of original technique.
Similarly, in temperature-fall period, be inserted into heat-conducting plate between different screen sections by as new high efficiency heat absorption body directly from glass
Glass screen intersegmental part siphons away heat, the time required to shortening its cooling.Through practicing, the glass screen section safety cooling time is from original technique
74~77h shorten to 50~53h.
In addition, the steel plate of excellent thermal conductivity, bulk temperature difference very little.Therefore glass screen section section each position contact
To heat source (or the heat being sucked away) it is almost the same.This also plays relaxation effect to screen intersegmental part lip temperature difference.It protects
The thermal stress of quality will not be had an impact because internal edge temperature difference is excessive by having demonstrate,proved the screen section during heating (or cooling).
2. debugging optimization
Mainly for the high temperature zone position debugging before compacting.In order to increase high-temperature area range, large volume fibre faceplate system
Make technique using the mode of adjustment electric furnace heating wire density, practice is got up fairly cumbersome.The present invention gives up this mode, is changed to
The mode of burner hearth cavity addition overcover.Specific implementation method is as follows:
1) appropriate increase, is done to defined fusion pressure temperature to adjust and (increase about 15~25 DEG C), keeps glass screen section temperature lower
Position can also reach suitable fusion pressure temperature.But in this way there is temperature drift in glass screen section portion；
2) a measurement temperature, is taken along short transverse to the burner hearth for being heated to the highest temperature, statistical data determines its longitudinal temperature
Field distribution；
3) suitable overcover (mineral wool etc.), is chosen, place mat is carried out along burner hearth cavity with certain thickness；
4) step 2, is repeated, until burner hearth upper and lower temperature difference is in OK range in the stipulated time.If temperature up and down
Difference is unsatisfactory for requiring, then continues to adjust overcover thickness or height.
3. equipment is simplified
The mold that large volume fibre faceplate manufacture craft uses, regardless of quality or all far super normal mold of volume.Therefore furnace
The hot melts such as thorax, furnace core and hydraulic press pressure equipment also must be increased correspondingly.The development or purchase of these equipment are one very big
Expense.
The novel die that large area fibre faceplate manufacture craft uses takes completely new structure design, is guaranteeing to use
Significantly reduce mould volume and quality while intensity.In addition, the plate components Combination Design that mold uses avoids greatly
The introducing of block steel makes its maintenance difficulties and cost decline (only needing to change components).New positioning system then ensure that
Mold also ensures preferable globality under the premise of components increase.
The successful optimization of mold use it can also in normal burner hearth.Therefore the production of large area fibre faceplate is not required to
Other special hot melt pressure equipment in addition to mold are developed, the reduction of development cost and the raising of equipment wide usage are realized.
The several major design detailed annotations of the fusion pressure mold are as follows:
1) introducing of high-performance heat-conducting plate
Muti-piece high-performance heat-conducting plate is introduced in the middle part of the mold, to realize the efficient of all glass screen sections of mould inside
Rate, a wide range of uniform heat conduction.In addition, there are also resistance to compression, the positioning of auxiliary screen section and molding effects for these heat conduction baffles.
2) design of mold " anti-to kill " structure
Since the thermal expansion coefficient of metal is much larger than glass, along with the effect of expanding with heat and contract with cold, metal die must in cooling
The fixed squeezing action by inner glass blank.If handling bad, gently if seizure or metaboly occurs, when serious
It may result in chunk glass and burst damage.General glass-forming die can be designed to deal with this by reasonable structure and ask
Topic.This mold is also such.
The design of " anti-to kill " structure is precisely in order to guarantee that mold can be dismantled smoothly after cooling and be designed.On mold
For square pressing plate, we are done segmentation design, while a sloping platform stage structure is inserted among pressing plate II and pressing plate III.Work as mould
When the certain pressure that tool is applied by top, due to the presence of step structure, pressing plate II and pressing plate III cannot produce in the horizontal direction
Raw relative displacement, the two can be considered the entirety that can not divide；And when top pressure removes, and mold starts cooling, if by
Lateral separation can occur for the extrusion stress generated to chunk glass, pressing plate II and pressing plate III, eliminate pressure.It both can guarantee in this way
Smoothly demoulding, and chunk glass can be protected not burst.
3) realization of mold entirety Assembly stability
Not only volume, quality are greater than general mold, inner components quantity to the mold of compacting large area fibre faceplate
Compare more.Therefore the problem of must be taken into consideration when the Assembly stability of mold is also design.
In this mold, a kind of " whole positioning " system is devised.The characteristics of system, is: when all positioned zero portions of mold
When part assembling finishes, mold is integrally stable and firm；And when a certain piece of components are removed in system, entire positioning system
Will be entirely ineffective, stripping operation can be readily accomplished.This Assembly stability for designing while ensure that mold and quick detachable property,
Has higher promotional value.
The principle of the positioning system is: connection type (this cooperation of loose fit is all used between any two components
Locating piece can be effectively prevented in mode and locating slot occurs to press from both sides dead problem), it is fixed that locating piece only guarantees wherein to have on one side with locating slot
Position contact, another side stay seam.Therefore adjacent components can generate relative displacement along specific direction.Baffle and pressure located above
The cooperation of plate is so that baffle past can only move right, and the cooperation of baffle and underlying pressing plate move to left baffle can only past
It is dynamic.In this way when three's assembly finishes, baffle will position completely.Other components are similarly.All positioning components are all linked with one another,
It finally joins end to end again, is achieved that the stabilization of mold entirety.As long as and one of positioning components of dismantling, so that it may according to
Certain sequence removes other components one by one, finally completes demoulding.
4) design of two side baffle of mold " reinforcing positioning bar "
In view of two side baffle of mold will be easy to happen Curved by biggish extrusion stress during heating pressure
Become, it is therefore necessary to design reinforcing rib structure (the simple baffle that thickeies can excessively increase mold weight) for it, it is strong to guarantee that it is used
Degree.
In this mold, we are not only that baffle is added to reinforcing rib structure, also by the structure and above-mentioned positioning system phase
In conjunction with the positioning of upper lower platen being carried out using the slot position between adjacent said rib, to complete the foundation of entire positioning system.
This way for making same structure functional diversities, dramatically saves mould volume, guarantees that it can make in normal burner hearth
With.
Cooperate the use of fusion pressure mold, the basic production process of large area fibre faceplate is as follows:
1) furnace temperature zone range is adjusted by the way of adding suitable overcover；
2) the complex light fibril met the requirements is drawn, and " vibration plate-laying " technique is used to carry out plate-laying；
3) the screen section sequenced is put into fusion pressure mold, after completing mold assembling, mold is put into normal burner hearth；
4) burner hearth passes through process control heating-cooling.Each temperature nodes refer to large volume fibre faceplate manufacture craft；Each stage
Time does scaled-back on its basis, according to specific equipment situation；
5) screen section is taken out in demoulding, successively carries out roughing and finishing to it, obtains finished product.
The present invention skips and first prepares the step of large volume fibre faceplate blank is cut again, straight using newly developed equipment

Product quality is big, and thermal conduction time is long, need a series of mating other special equipments come using the problems such as, present invention employs a kind of completely new
Fusion pressure mold design.The mold uses new positioning and pressure-bearing disassembling system, and use intensity is high, and volume mass is small, Ke Yipei
It closes normal device to use, also very easy to process and maintenance.Meanwhile new internal structure enhances mold system in entire fusion pressure
The capacity of heat transmission in the process is the key that fusion pressure and annealing process time is greatly shortened.According to preliminary test, new mold is used
Fusion pressure and annealing are carried out, can shorten the process time is total to about 33~35h.
Present invention uses new furnace temperature zone range testing and measuring technologies.It needs for the prior art through continuous disassemblerassembler
